Abstract
In an image processing method, a first raster having a first resolution is divided into a plurality of sub-sampling cells each containing a selected number of neighboring pixels. A pixel from each of the sub-sampling cells is selected in a periodic or quasi-periodic pattern biased toward selecting a pixel position within each sub-sampling cell that is distal from a selection position within at least one neighboring sub sampling cell. The selected pixels define a second raster having a second resolution lower than the first resolution.
